SPECIFICATION forming part of Letters Patent N 0. 643,866, datedFebruary 20, 1900.

Application filed May 5, 1899- Serial No. 715,707. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH O. DECKERT, of the city of Philadelphia,inthe county of Philadelphia, State of Pennsylvania, have invented a newand Improved Copy-Book, of which the following is a full, clear,andexact description, reference being made to the drawings accompanyingthis specification.

The objects of my invention are to provide a book in which copies ofletters and other documents can be made on the sheets of tissue-paperforming part of the book in the same manner as in books at present inuse that is to say, by the ordinary transfer of the inked writing orimpressions from the original matter desired to be copied to thetissuesheets of the book, such sheets being, as is customary, firstdampened to receive such transfer, or copies of writings may be madeupon the tissue-paper sheets of my book by placing under the sheet to beimpressed an oiled-paper-backing with a carbon-sheet interposed betweenthe sheet to be written upon and the tissue-sheet upon which the carbonreproduction is to be made'and then writing, as usual, on theletter-head sheet or other sheet in the usual manner where atransfersheet is employed. In addition to such manner of employing mybook the construction of it, in cooperation with its perforated leaves,is such as to permit of its use in another and novel manner-namely, theremoval of the sheets from the book and the employment of same in atype-Writing machine for the impression upon them of a carbon-copy ofany desired writing from the original sheet and the subsequentreinsertion of the sheet in the book and locking same therein by meansof the locking device forming part of the book.

Reference is hereby made to the accompanying drawings, forming part ofthis specification, which together illustrate the nature andconstruction of the invention.

Figure 1 is a plan view showing the book open, the back pieces beingexpanded and the leaves or sheets removed from the book. The sliding keyin this figure is drawn out to the position which permits theimpaling-posts to enter the enlarged openings in the key when the upperback piece and its key is pressed down upon said posts. Fig. 2 is aperspective view showing the book partly filled with leaves or sheetsimpaled upon the posts, the upper back piece, with its key, having beenpressed down upon the posts and the key moved into its closed position,so as to effect the locking of the device, and in this view is alsoshown a flat spring, suitably curved, which is interposed between theupper back piece and the pile of sheets fora purpose to be hereinaftermentioned. Fig. 3 is a separate plan view of the sliding key. Fig. 4 isa view of one of the perforated sheets. Fig. 5 is a plan view of analternative construction,the book being fully opened,

showing a single centrally-disposed impalingpost, a key having a singlecentrally-disposed opening for engagement therewith, the rivets andslotted openings in the key for engagement therewith in such alternativeconstruction being disposed nearer the ends of the up per back piece andkey, respectively, than when two impaling-posts are employed. Fig. 6 isa detailed view of a portion of the lowerback piece and one of theimpaling-posts. Fig. 7 is a separate view of the spring already referredto, and Fig. 8 is a longitudinal section through a portion of the book.

The book is provided with two covers 1 and 2, flexibly attached,respectively, to the back pieces 3 and 4., which in turn are flexiblyattached to the end piece 5.

The back piece 1 is provided with a sliding bar or key 6, which in turnis provided with slots 7 and 8 and is movably attached to the back piece1 by means of rivets or screws 9 and 10, which pass through said slotsand are firmly secured to said back piece. Said sliding bar or key isalso provided near its oppoposite ends with openings 11 and 12, whichhave their sides parallel throughout part of their length and terminatein enlarged circular apertures and shown at 13 and 14, which latterregister when the bar or key is drawn out to its outermost position,with posts at tached to the other back piece.

15 and 16 are posts which are attached to back piece 2 and are slotted,as shown at 17 18, near their upper ends, leaving the heads 19 20,which, as stated, register with openings 13 14 in the sliding bar whenthe latter is drawn out to its open position, and with recesses A and 13formed in the upper back piece. The sliding bar or key is, forconvenience of its manipulation, bent at a right angle to its out-erend, as shown at 21.

The leaves or sheets 22 of the book are provided near their inner edgeswith apertures or holes 23, which register with each other and adaptthem to be telescoped over the impaling-posts 15 16.

The book is provided also with an index 24, which may be stitched orotherwise attached to the upper cover 1.

The manner of combining the sheets with the bookthat is, by telescopingsame over the impaling-posts-is obvious, and the man ner of lockingtheposts together and again unlocking them, so as to permit the removaland reinsertion of one or more leaves, will be readily understoodthat isto say, the leaves having been placed on the impaling-posts, the slidingkey occupying at the time the position shown in Fig. 1, the back piece3, with the sliding key, is pressed down upon the impaling-posts, theheads of which enter and pass through the enlarged openings 13 14 of thekey and into recesses A B in the upper back piece. The key then beingpushed inwardly causes the engagement of the slots 17 18 of the postswith the slotted openings 11 12 of the key, thus eilecting the lockingof the device.

Referring to Figs. 2 and 7, which illustrate or pile of leaves, which,as seen, presses down upon the leaves and obviates such liability.

While I have described and shown a sliding key having two slottedopenings adapted to be engaged with two slotted posts and have shown anddescribed sheets or leaves having two perforations near their innerends, I do not wish to confine myself to such precise construction,since it is manifest that I may employ leaves having a singleperforation centrally disposed combined with a centrallylocated post andkey with a single centrallydisposed slotted opening for enga ement withsuch key, as illustrated in Fig. 0; but I pre fer the construction firstherein described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In a copy-book, the combination of the covers 1 and2, the back pieces 3 and .1: having flexible connection therewith, theend piece 5 flexibly connected to the said back pieces, headed pinslocated on the inner face of one of the back pieces, a key having slotsthrough which the headed pins pass thereby permitting a sliding movementof the said key, the key also having a slot provided with an enlargedopening, a headed post attached to the other of the said back pieces andadapted to engage the slot of the key for the purpose of 1 interlockingthe parts, the said back piece 3 being provided with a recess to receivethe head of the said pin, and a spring interposed between the upper backpiece and the leaves of the book, substantially as described.

In testimony whereof I have hereunto atfixed my signature, in thepresence of two witnesses, on this 9th day of March, A. D. 1899.
